QUICK ANSWER
Is it possible to convert ARC to CAB?
No - not a direct conversion.

ARC holds compressed arbitrary files from 1985-era BBS archives; CAB (Microsoft Cabinet) is a Windows Setup format where each file entry must carry deployment context - sequencing, destination paths, and installation flags - that no converter can invent from an ARC archive. The practical goal is to extract the files and repack them as ZIP or 7z instead.

Why convert ARC to CAB?

An ARC Compressed Archive (1985) bundles files without structural metadata beyond filenames. A CAB file is a Windows-specific installer container where Microsoft Setup tools expect each entry to carry deployment instructions. These formats serve entirely different purposes, and this pairing appears in conversion databases from automated generation rather than any real user need.

Quality & what to watch

  • CAB files require installation directives and are built with Microsoft's MAKECAB tool - you cannot simply place arbitrary files into a CAB container.
  • 7-Zip does not reliably open classic SEA ARC files; use PeaZip or IZArc for the extraction step.
  • ZIP opens natively on Windows, macOS, and Linux - a far better target than CAB for preserving old archive contents.

Frequently asked questions

Is there any converter that turns ARC into CAB?
No legitimate one exists; CAB files require deployment metadata that cannot be generated from a generic file archive.
Why do some sites list ARC to CAB as possible?
Conversion sites often generate format pairings algorithmically; both ARC and CAB store files, so the pair passes a surface-level check even though the conversion is meaningless.
What is the best modern alternative to an old .arc archive?
ZIP - it opens natively on every modern OS without extra software and is losslessly repacked from the .arc contents using PeaZip or IZArc.
